@lap1nou with the PRs you made on exegol with the fzf aliases it gave me the idea to provide commands directly from the haiti gem / package with more powerful options. You can take a look at b967a52 if you want to analyze what I did or install the gem (see development + git) from the master branch to try it out. I believe that your aliases are still relevant even now because they offer color (I choose not to in my commands) as well as taking advantages of another exegol alias like fzf-wordlist. I wanted to thank you for that great idea.
